May i know where to buy cheap and good essential oil ? I heard of YLEO theres membership for it anyone can guide me ?

I don't think its a loyalty programme membership, i think it's a resellers programme! https://www.youngliving.com/en_SG/opportunity/compensation-plan essential oils are available widely in singapore, it really depends on what kind you're looking for as well :) what are you intending to use it for?
